Lipopolysaccharide - Wikipedia
LPS is a major component of the outer cell membrane of gram-negative bacteria, contributing greatly to the structural integrity of the bacteria and protecting the membrane from certain kinds of chemical attack.

Apr 17, 2023 · Lipopolysaccharides (LPS) are important outer membrane components of gram-negative bacteria. They are large amphipathic glycoconjugates that typically consist of a lipid domain (hydrophobic) attached to a core oligosaccharide and a distal polysaccharide.
Function and biogenesis of lipopolysaccharides - PMC
Gram-negative bacteria are characterized by an envelope that contains two membranes: an inner membrane (IM) that surrounds cytoplasmic components, and an outer membrane (OM) that separates the cell from its environment.
Pushing the envelope: LPS modifications and their consequences
May 29, 2019 · The defining feature of the Gram-negative cell envelope is the presence of two cellular membranes, with the specialized glycolipid lipopolysaccharide (LPS) exclusively found on the...
Lipopolysaccharide - an overview | ScienceDirect Topics
The lipopolysaccharide (LPS) is a major component of the bacterial outer membrane and demonstrates cytotoxicity. The LPS consist of two parts, a hydrophobic lipid responsible for cytotoxicity and a hydrophilic polysaccharide accountable for serological properties [200] .
